Mars Photography By Mars Reconnaissance Orbiter

• Water ice in ice cap measured
Results published in 2009 of radar measurements of the north polar ice cap determined that the volume of water ice in the cap is 821,000 cubic kilometers (197,000 cubic miles), equal to 30% of the Earth's Greenland ice sheet.
• Ice exposed in new craters
An article in the journal Science in September 2009, reported that some new craters on Mars have excavated relatively pure water ice. After being exposed, the ice gradually fades as it sublimates away. These new craters were found and dated by the CTX camera, and the identification of the ice was confirmed with the Compact Imaging Spectrometer (CRISM) on board the Mars Reconnaissance Orbiter (MRO). The ice was found in a total of 5 locations. Three of the locations are in the Cebrenia quadrangle. These locations are 55.57°N 150.62°E; 43.28°N 176.9°E; and 45°N 164.5°E. Two others are in the Diacria quadrangle: 46.7°N 176.8°E and 46.33°N 176.9°E.
